Measuring 'g' is crucial in various contexts, particularly in science and engineering. The standard acceleration due to gravity, symbolized as 'g', equals 9.8 m/s². To measure it, you can perform a simple experiment using a pendulum. Measure the length (L) of the pendulum and the period (T) it takes to complete one swing. Use the formula: g = 4π²L/T². This method provides a practical way to determine 'g' accurately.
